South Korea targets $540 billion（約86兆円） AI chip hub by 2030, faces power crisis

South Korea has announced an ambitious plan to establish the Honam semiconductor industrial complex in its southwestern region, with an estimated cost of at least 800 trillion won ($540 billion（約86兆円）). The project is scheduled for completion by the end of 2030, marking the close of President Lee Jae Myung's term. It is central to Lee's broader economic strategy to distribute the gains of the AI semiconductor boom beyond the prosperous Seoul metropolitan area.

However, the project faces substantial hurdles rooted in its physical infrastructure demands. Companies involved in the plan, including Samsung Electronics, will need to locate and secure new energy sources to power the complex. Local opposition to the project's massive power and water requirements is emerging as one of its biggest obstacles. The scale of these resource demands—both electrical and hydrological—presents a complex challenge for regional authorities and the companies driving the initiative. Resolving how to supply adequate power while addressing community concerns about water usage will likely determine whether the ambitious four-year timeline can be met.

South Korea's Honam semiconductor complex represents an ambitious attempt to decentralize the country's semiconductor leadership and capitalize on the global AI chip boom. By situating the hub in the southwest—outside the prosperous Seoul metropolitan area—President Lee aims to share the economic gains of advanced chip manufacturing across the nation. The $540 billion（約86兆円） investment underscores the stakes: the country views semiconductor capacity as critical to its economic future.

Yet the project faces a fundamental infrastructure challenge that the body identifies as potentially its "biggest obstacle." The complex's massive power and water demands collide with regional resource constraints and local opposition. Samsung Electronics and other companies involved must locate and secure new energy sources—a non-trivial engineering and political problem that could delay or derail the timeline. The four-year window (through 2030) is aggressive given these constraints, suggesting that resolving the energy question will be the critical test of whether the hub materializes on schedule.
